Cryptography and Shift Registers
Shift registers are at the heart of cryptography and error-correction. In cryptography they are the main tool for generating long pseudorandom binary sequences which can be used as keys for two communicating parties in symmetric cryptography. Practically all military cryptography makes use of them. Shift registers are also fundamental in signal analysis and frequency hopping, most recently in c...
متن کاملShift Registers
A homomorphism of the de Bruijn graph that maps a graph of order n onto one of order n -1 and its applications to the design of nonsingular feedback shift registers are discussed. The properties preserved under this mapping suggest a new design technique whose main advantage is due to the fact that the problem of designing a desired n-stage shift register may be reduced to a problem of order n ...
متن کامل2-Adic Shift Registers
Pseudorandom sequences, with a variety of statistical properties (such as high linear span, low autocorrelation and pairwise cross-correlation values, and high pairwise hamming distance) are important in many areas of communications and computing (such as cryptography, spread spectrum communications, error correcting codes, and Monte Carlo integration). Binary sequences~ such as m-sequences, mo...
متن کاملTransistor Shift Registers
Three different types of high-speed transistor shift registers are discussed. The high speed (3 to 5 microseconds per shift pulse) is made possible by the use of oneand two-transistor nonsaturating bistable circuits. The design of these circuits and their limitations when used .is shift register stages is discussed CAMBRIDGE MASSACHUSETTS
متن کاملAlgebraic Feedback Shift Registers
A general framework for the design of feedback registers based on algebra over complete rings is described. These registers generalize linear feedback shift registers and feedback with carry shift registers. Basic properties of the output sequences are studied: relations to the algebra of the underlying ring; synthesis of the register from the sequence (which has implications for cryptanalysis)...
